TRUSS.

SPECIFICATION forming part of Letters Patent No. 269,571, dated December26, 1882.

Application filed May 8, [882. (No model.)

To all whom it may concern.-

Be it known that I, JAMES EDGAR HANSON, a citizen of the United States,residing at Schoolcraft, county of Kalamazoo, State of 5 Michigan, haveinvented a new and useful Truss, of which the following is aspecification. My invention relates to trusses especially designed forsupporting abdominal hernia.

It has for its object certain improvements [0 whereby the pad is moreconveniently operated than heretofore.

In the drawings forming a part of this specification, Figure l is aperspective view of a truss containing my improvements, andoFig. 2

is a cross-sectional and edge view on a line with the edge of spring 8in Fig. l.

The truss-stock F F is covered with leather or other suitablemateriahand has loops L L, with which means may be connected to secure 2said stock around the person. The end ofthe stock A with which the pad Bis connected is formed square.

D isa movable collar, located on said square portion, and is held ingiven, positions by 2 5- means of screw a. Th us the pad may be nicelyadjusted to the exact location of the hernia, as in former devices.

A ratchet, R, is rigidly sesis a spring secured to the pad, its upperend being adapted to engage the ratchet R.

' This holds the pad and itssupportat any given pressing hard on therupture, as shown by dot-' ted lines in Fig. 1, this pressure may bereleased by raising the spring S with said lever e, and,by swelling outthe body, again throwing the pad outward, as shown by the plain portionof said figure.

As many pads as desirable may be located on a single stock and extendedabove or below the same, in accordance with the number and location ofthe hernia.

Having thus described my invention, what I claim is- A truss-stockprovided with the ratchet, the pad, pad-support, and spring-pawl, incombination with the cam-lever for disengaging the pawl from theratchet, all substantially as set forth.
